I registered for a half marathon. It's 5/31. It's women only and there will be walkers so I know I won't be last

I know this is far out from the event but it is less to register early. Also, I tend to be more inspired for training when I have a specific date to be ready by. I've been pretty much in training "holding pattern" while the holidays are here because I've been pretty busy. Holding pattern is 4-5 mile run on my long day and the other days are 2.5-3.5 miles. I'll start increasing in January.

I'm happy but part of me is thinking "oh no, what did I do?"
